Specificity of oligoclonal IgG bands in sera from chronic relapsing experimental allergic encephalomyelitis guinea pigs.

Abstract

The specificity of oligoclonal IgG in sera from chronic relapsing EAE guinea pigs was determined by using imprint electroimmunofixation. The response of oligoclonal IgG to spinal cord and Mycobacterium tuberculosis appeared to be equal in animals sacrificed during first remission and in those sacrificed after recovery from acute EAE. In contrast, in animals sacrificed during or after the first relapse, the oligoclonal IgG seems to be directed predominantly against spinal cord. In imprint electroimmunofixation, the oligoclonal IgG specific to spinal cord did not react with guinea pig liver and kidney. In addition, activity to spinal cord could be removed from sera by absorption with spinal cord but not with kidney or liver.
